[Bug 1727956] Re: Installer crashes when installing over existing LUKS or LVM

[Phillip Susi]

Confirmed: having an existing LUKS or LVM install and trying to
reinstall over it causes ubiquity to try to install grub to /dev/dm-0
instead of /dev/sda, which fails.


** Summary changed:

- Installer crashes when installing over existing LUKS encryption
+ Installer crashes when installing over existing LUKS or LVM

** Changed in: grub-installer (Ubuntu)
   Importance: Undecided => Critical

** Changed in: grub-installer (Ubuntu)
